Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Determine irrigation shifts

  1. The irrigated area is subdivided into the smallest units capable of individual irrigation and area, and irrigation equipment characteristics are noted for each
  2. Each unit is defined for its soil irrigation capability
  3. The crop/plant water requirement is defined for each unit
  4. Units requiring similar irrigation are combined to form a shift that does not exceed the water delivery capacity of the property irrigation infrastructure
  5. Water volume required to meet irrigation needs over specified period is determined

Instructions to Assessors

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this Unit

The evidence required to demonstrate competency in this Unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:

estimate water availability for plants/crops

determine irrigation shifts and rates

test soil moisture levels

monitor and record irrigation data

evaluate effectiveness of irrigation.

Context of and specific resources for assessment

Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.

Required Skills and Knowledge

Required skills include:

Ability to:

access and discuss irrigation schedule

interpret the information in an irrigation schedule

liaise with other work areas

consult with appropriate senior personnel or consultants

soil moisture levels

watertable level

water quality

signs of plant nutrient deficiencies

climatic conditions

frost risk

plant varietal characteristics and requirements

soil type and depth

crop stage and requirements if applicable

symptoms of water stress

effective root depth

implement the irrigation schedule. This may include consideration of:

resources, including operators with appropriate skills

application rates

timing and length

report and/or record problems and/or corrective action taken

monitor the effectiveness of irrigation activities

monitor the environmental impact of irrigation activities

identify, rectify and/or report environmental non-compliance

maintain workplace records

maintain work area to meet housekeeping standards

implement and follow relevant enterprise OHS and environmental policies and procedures.

principles of soil moisture monitoring eg volumetric soil moisture content, percentage compared to soil moisture tension

water budgeting tools

Range Statement

The range statement relates to the Unit of Competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Irrigation schedules may include:

any system that schedules irrigation water through a growing season. Schedules may be based on:

soil-based systems, monitoring soil moisture

climate-based systems

plant-based systems, monitoring the plant

a combination of the above.
